洗便器の改良に関する。[Detailed description of the invention] The present invention is a flush toilet, in particular, a type in which flush water is distributed and supplied to a rim water injection hole for flushing the toilet bowl and a fountain hole opening below the surface of a trap reservoir for draining waste. Regarding improvements to flush toilets.

る。 Conventionally, there are types called siphon type, siphon jet type, and blowout type which have a rim water injection hole and a water fountain located below the trap water surface. FIGS. 4 and 5 show a siphon-type toilet with a structure that drains water toward the wall. An annular rim is attached to the upper end of the toilet bowl 32 so as to communicate with the water supply chamber 30 connected to the water supply source through a rim communication hole 31. A water passage 33 is formed, and a rim water injection hole 34 is bored in the water passage so that water can be sprayed toward the toilet bowl 32 for washing. Further, a water fountain hole 36 that opens below the water reservoir surface of the trap section 35 is provided in communication with the water supply chamber 30, and water is spouted from the water fountain hole toward a drainage channel 37 to wash away and discharge dirt. Further, the jet flow from the water fountain hole 36 can promote the siphon phenomenon, especially in siphon type and siphon jet type toilet bowls.

ものは、給水室３０とリム通水路３３とを連絡す
るリム連絡孔３１、及び噴水孔３６の開口面積の
大小であり、開口面積が大のほうには多量の吐水
が、又、開口面積が小のほうには少量の吐水がな
されて二吐水量に一定の比を持たせることができ
る。 In the toilet bowl configured as described above, the ratio between the amount of water discharged from the rim water injection hole 34 and that from the water fountain hole 36 is set in order to optimally clean the toilet bowl 32 and efficiently push out waste from the drainage channel 37. It is necessary to maintain a constant value. What determines this water discharge ratio is the size of the opening area of the rim communication hole 31 that connects the water supply chamber 30 and the rim passageway 33, and the water fountain hole 36. However, a small amount of water is spouted to the one with the smaller opening area, so that a constant ratio can be maintained between the two volumes of water spouted.
また二方向からの吐水量の比は便器の形式や洗
浄水流路細部の構造などにより異なるが、一般に

さくして開口面積が狭くなるように構成してい
る。 Although the ratio of the amount of water spouted from the two directions differs depending on the type of toilet bowl and the detailed structure of the flushing water flow path, generally speaking, the amount of water spouted from the water fountain 36 is higher than that from the rim water jetting hole 3.
I am trying to make it more than that from 4. Therefore, from the above-mentioned opening area relationship, the rim water injection hole 34
In order to reduce water discharge from the rim, the rim communication hole 31 is made small so that the opening area becomes narrow.

で膨張して騒音を発生するという欠点がある。 In the structure described above, cleaning water supplied from the cleaning tank, flush valve, etc. enters the rim passageway 33 from the water supply chamber 30 through the rim communication hole 31. At this time, there is a drawback that air bubbles mixed into the water and compressed in the water supply chamber 30 expand and generate noise when they flow into the rim passageway 33 through the rim communication hole 31, which has a small opening area. .
本考案は以上のような問題を解消しようとする

側への流量比も洗浄に好適な値に設定できる。 Water flowing from the water supply chamber to the rim passageway is subject to flow path resistance by the flow path resistor, but by providing the rim communication hole with an opening area that can compensate for the decrease in flow rate toward the rim passageway side due to this, At the same time, the flow rate drop toward the rim passageway side is eliminated, and at the same time, the inflow velocity into the rim passageway is reduced to suppress rapid expansion of bubbles and prevent the generation of noise. In addition, by creating a flow path structure in which the flow rate towards the rim passageway side is smaller than the flow rate towards the fountain hole side, the flow rate ratio between the fountain hole side and the rim passageway side is set to a value suitable for cleaning. can.

る。 The water supply chamber 2 is located in front of the opening area of the rim communication hole 3.
A barrier 11 serving as a flow path resistor is formed and extends downward by a required amount from the upper wall 2a. In this embodiment, the rim communication hole 3 is provided eccentrically from the axis of the toilet main body as shown in FIG.
is formed in a cross section that connects the partition wall 2b on the side of the rim passageway 5 and one side wall 2c in the axial direction.

で騒音の発生を低減させることができる。 With the above configuration, the cleaning water supplied from the water supply source to the water supply chamber 2 passes through the rim communication hole 3 and the side passage 12 in two directions to the fountain hole 7, as shown by arrows A and B in FIGS. 1 and 2. Divert to. At this time, as shown in FIG. 1, the flow line of water heading toward the rim communication hole 3 is bent by the barrier 11, which acts to increase the flow resistance, and therefore reaches the rim communication hole 3. The water flow rate decreases. Therefore, because the velocity of the flow flowing into the rim passageway 5 from the rim communication hole 3 is small and because the opening area of the rim communication hole 3 is large, when the flow flows into the rim passageway 5 after passing through the rim communication hole 3. Since the flow path expansion degree can be reduced and the expansion of compressed bubbles can be suppressed, noise generation can be reduced.

及び障壁１１の寸法形状を決定する。 As mentioned above, it is necessary that the amount of water discharged from the rim water injection hole 6 and from the water fountain hole 7 satisfy a certain ratio. The flow path resistance of the barrier 11 that affects the flow velocity of the rim communication hole 3 is calculated in advance.
and determine the size and shape of the barrier 11.
即ち、障壁１１を設けて流路抵抗を増して流速
を減じた分リム連絡孔３の開口面積を水が流入し
やすいように大きくしてやれば良く、これは「流
体の連続の式」を用いれば大概の算定ができる。 In other words, by providing the barrier 11 to increase the flow path resistance and reduce the flow velocity, the opening area of the rim communication hole 3 can be increased to make it easier for water to flow in. This can be done using the "fluid continuity equation". Can do most calculations.

同じく６：４とすることができた。 To show this in actual dimensions, the opening of the rim communication hole 31 of the flush toilet described in the conventional type is 15 x 30 mm.
The amount of water discharged from the rim water injection hole 34 and the water fountain hole 36
The ratio of the amount of water discharged was approximately 6:4. On the other hand, in the toilet bowl of the present invention, if the barrier 11 was provided and the opening of the rim communication hole 3 was set to 17 x 40 mm, the above water discharge ratio could be similarly set to 6:4.
